标题使用ansi颜色控制代码

下面是控制颜色的代码

// Reset
    public static final String RESET = "\033[0m";  // Text Reset

    // Regular Colors
    public static final String WHITE = "\033[0;30m";   // WHITE

在打印日志函数的 message 前面加上颜色定义字符串，在 message 后面加上重置颜色的字符串。为了方便观察，日志改色的效果，这里进行了两次打印来作对比。

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Console {
    public static Log getInstance(String name) {
        return new Log(name);
    }

    public static class Log {
//        private org.apache.commons.logging.Log log;
        private Logger log;

        public Log(String name) {
//            log = LogFactory.getLog(name);
            log = LoggerFactory.getLogger(name);
        }
        public void debug(String str) {
            log.debug(BLUE + str + RESET);
            log.debug(str);
        }
        public void info(String str) {
            log.info(GREEN + str + RESET);
            log.info(str);
        }
        public void warn(String str) {
            log.warn(YELLOW + str + RESET);
            log.warn(str);
        }
        public void error(String str) {
            log.error(RED + str + RESET);
            log.error(str);
        }
    }
    //此处省略颜色代码的定义
}

通过打印可以看到，并不是整行日志的颜色都会改变。仅有message部分的颜色变了
